I've been doing a lot of Googling on this topic & found this page, which seems to describe exactly the problem I'm having:
http://www.jaxtut.com/Navigation.jsp It suggests calling resetFromSession(), though it doesn't give an implementation & this method doesn't seem to be part of Wicket. Has anyone found a way to reset the form after the model has changed & the form re-rendered thru Ajax? If there isn't a way to do this in Wicket, is there a "Wicket wish list" to add it to?
